Initially I thought we had a language barrier cause I didn't understand your statement for obvious reasons - but you may be on to something.
Bottom line is looking back I knew my systems worked well in a low volatility environment with very low interest rates. Now that that changed I guess I don't really know how well or if they will work at all - based on the Ytd P&L one can argue they don't.
Ok so it looks like you need to re-assess the profitability of your trading system to determine how well it works in all market environments. The market environment is dynamic and changes from time to time and not all trading systems work equally well. And from what you find out, you may need to go back to the drawing board to redesign a new trading system or modify the existing one to accommodate the current market situation.
